Muhammad Ali Heavyweight Boxing was released in 1992, most copies of the game came with a trading card of Ali. This game allows 3D movement around the ring.
There are two basic modes: exhibition and tournament. Tournament has the player start from rank 10 and move to the top. There is a password system to save progress. There are basic options such as changing how many knockdowns are required for a TKO and how long rounds are.
There are two control styles. There is arcade style, where it is simplified to light punch and heavy punch. There is also simulation style, which allows players to input exactly which punch they want to throw. This is controlled by holding down the A button for the left hand and C button for the right hand, then the directional pad to throw a punch.
There are two meters on the screen that controls a punch's speed and power. This game is purely based on the player boxer's stamina. If they throw too many punches, their bars will get low and they will be able to be knocked out. There is damage to each boxer shown between rounds.
